If a falling mass hits a sequence of stationary supports and breaks them, what is the effect of adding mass to those supports?  Do the masses result in more supports being broken because of the increased weight or does the conservation of momentum slow the falling mass so much that the reduced kinetic energy results in fewer broken supports?

Without added mass an average of 17.75 toothpicks were broken in 4 drops.

With various configurations of mass an average of 6.64 were broken in 14 drops.

So the mass reduced toothpick destruction by 63%.

The tilt in the washers means the falling mass does not accelerate the entire washer in a uniform manner.  A better support system needs to be developed.

But is common understanding of this phenomenon relevant to world politics?

Well there were these buildings in New York I think that supposedly underwent top down gravitational collapses because of airliner impacts and fires.  And this seems to have stirred up a bit of a ruckus with lots of people getting killed in Iraq.

So I was wondering if a top down gravitational collapse was actually possible but part of the problem is that I don't know the distribution of steel and concrete in the buildings.  I figure the steel should get stronger and heavier toward the bottom but I don't know how fast.

After I shot most of the video it occurred to me that by using wire instead of toothpicks I could vary the strength at each level with the gauge of the wire.  Maybe solve that tilt problem too.

But what would happen if it were PROVEN that it was IMPOSSIBLE for the top 11% by volume of a skyscraper to crush the bottom 85%?  That 11% by volume might be less than 5% by weight.

I think you should stick this thread somewhere else where more people will read it.

Where do you suggest?

You are welcomed to create links back to this thread.

I didn't know what the reaction would be on this site.  There is a lot of anti-9/11 sentiment out there.  I have had two threads locked on other sites.

What I find odd is so many people who claim to be interested in science do not find the whole 9/11 business fascinating.  Shouldn't it be obvious that the distribution of mass and the distribution of steel are important to skyscraper design?  So how could the top 10% crush the rest in less than 18 seconds?  "Curiouser and curiouser!" cried Alice.  [91]

What about the other 5%?

Okay, I've had a look at that video. I don't know anything about the physics behind this so my comments are most likely to be of no use to anybody. []

But from what I understand, tell me if this is right or not. What you are saying is that the engineers did not design the building properly correct? So why do you think the building collapsed?

The distribution of mass in skyscrapers cannot be uniform. They are bottom heavy because they must get stronger toward the bottom to hold the weight above.

No, I would say the building never should have collapsed.  There was nothing wrong with it.  But the idea that the top 10% could crush the rest in less than 18 seconds is utterly absurd.

But the inherent physics of skyscrapers should have told everyone that planes could not destroy the buildings that fast.

Yes, I've still got it.

Then I don't understand your question:

What I meant was: so what happened to the building if, as you say:

the building never should have collapsed.  There was nothing wrong with it.  But the idea that the top 10% could crush the rest in less than 18 seconds is utterly absurd.

...the inherent physics of skyscrapers should have told everyone that planes could not destroy the buildings that fast.

I supplied you with a video about WHAT DID HAPPEN.

I am not approaching the problem from that perspective however.  I am attrmpting to demonstrate that the Official Story is IMPOSSIBLE.  Due to the Conservation of Momentum and the way Mass Must be DISTRIBUTED in a skyscraper it should be IMPOSSIBLE for the top 10% by volume of a skyscraper to crush the bottom 85%.  Therefore SOMETHING ELSE had to be responsible for the destruction.  I am not trying to say what that Something Else was.  That is other people's problem.  But no official source has given us the distribution of steel and concrete of the WTC towers in SEVEN YEARS.  We should have had it in SIX MONTHS.

Perhaps your experiment did not accurately model the situation? You are suggesting that the distribution of mass was not bottom heavy so the building collapsed, just like your toothpicks?

Excuse me?

I said skyscrapers must be bottom heavy.  The WTC was bottom heavy.  Lon Water has a site showing the cross section of the columns.

http://wtcmodel.wikidot.com/system:list-all-pages

But that means skyscrapers get stronger going down.  My toothpicks were the SAME going down.  Therefore my model should be MORE LIKELY to collapse than the towers.  But my model stopped the falling mass even faster with mass than without.  Therefore distribution of mass should be important to the analysis of the WTC.

So why don't we have that information made public from an Official Source in SEVEN YEARS?

Ohhh!
Sorry, excuse me. A bit of misunderstanding from my part. [:I]
But now I see. Now isn't that wierd? []
What kind of a plane was it? How many passengers were on it and how many people were in the building? Are we given this information?
